I am learning to create custom JSF components and have been successful in creating simple ones. One thing I would like to know is that whether there are any naming conventions to be followed while defining <component-family> and <renderer-type> for your component?
For e.g. for combo box the <component-family> is javax.faces.SelectOne. It looks like a Java class but I was unable to find any such class in JSF API.
They do indeed not necessarily represent class names. They are just identifiers. The javax.faces prefix hints in this case merely that it's part of standard JSF API. The same prefix is used everywhere else in standard JSF API. PrimeFaces components use org.primefaces prefix, OmniFaces components use org.omnifaces prefix, etcetera.
You're fully free in choosing your own for your component library. You should only gurarantee that it shouldn't possibly conflict with a 3rd party one which may be mixed by the enduser. Like as with package structure of Java classes, it'd make sense if you choose for com.naveen prefix or whatever what/who represents the owner/developer of the component library.
The same approach as Java packages (and Internet domain names) is a very sensible way of guaranteeing uniqueness (you know, identifiers are supposed to be unique).
